Agnesiella (D.) biprotrusa Huang & Zhang sp. nov. ( Figs 25–28 View FIGURES 17–32 , 55 View FIGURES 49–60 , 106–113 View FIGURES 106–113 )

Measurement. Male, 3.2–3.40 mm (including wings).

Description. Body yellowish-brown ( Figs 25, 26 View FIGURES 17–32 ). Face mostly light brown, frontoclypeal area with dark brown transverse stripes, anteclypeus blackish brown, lorum brown, genae largely blackish brown ( Fig. 28 View FIGURES 17–32 ). Vertex orange-red medially with a pair of dark brown patches along anterior margin. Pronotum with brown median area, remaining parts largely dark brown patches; triangles blackish brown, scutellum pale yellow outer margins of scutum and scutellum orange-red ( Fig. 27 View FIGURES 17–32 ). Forewing with one brown patch each at base, middle and apical part in basal 2/3; 1st, 3rd apical cells and ScP+RA vein with some brown patches, brochosome area yellowish-brown with a blackish brown patch at each end ( Fig. 55 View FIGURES 49–60 ).

Abdominal apodemes extending to apex of 5th abdominal sternite ( Fig. 106 View FIGURES 106–113 ). Male pygofer with a long fine setal group near posterior margin, several small rigid setae clustered on protruded posterodorsal margin; a small horn-like pygofer process on posterior margin ( Figs 107, 108 View FIGURES 106–113 ). Subgenital plate with distal part bearing some long fine setae and small rigid setae; a distinct protrusion subapically, apex with peg-like setae ( Figs 109, 110 View FIGURES 106–113 ). Style with a very small subapical process ( Fig. 111 View FIGURES 106–113 ). Connective without prominent central lobe ( Fig. 109 View FIGURES 106–113 ). Aedeagal shaft sinuate, with a plate-like ventral expansion apically, a bifurcate ventral process at middle with upper branch longer than lower branch, both digitiform branches directed dorsally ( Figs 112, 113 View FIGURES 106–113 ).

Specimens examined. Holotype: ♂, CHINA, Sichuan Province, Moxi County, 1600m, 4 Nov 1999, coll. I. Dworakowska. Paratype: 1♂ 1♀, same data as holotype ; 1♂, CHINA, Yunnan Province, Gongshan Derung and Nu Autonomous County , Bingzhongluo Town , 1700m, 12 Jun 2019, coll. Lü Lin ; 2♂ 1♀, CHINA, Yunnan Province, Gaoligongshan National Nature Reserve , 2050m, 18 Jun 2022, coll. Junjie Wang ; 2♂, CHINA, Yunnan Province, Huanglianshan National Nature Reserve , 1650m, 10 Jun 2023, coll. Lü Lin.

Remarks. The new species resembles A. (D.) longisagittata in the male genitalia, but differs in having a sinuate aedeagal shaft and the bifurcate ventral process situated at the midlength of the shaft ( Fig. 112 View FIGURES 106–113 ).

Etymology. This specific epithet is derived from Latin words “bis” and “protrudere”, referring to the bifurcate ventral process of the aedeagal shaft ( Figs 112, 113 View FIGURES 106–113 ).
